WILLIAM H. PAIGE, OF SPRINGFIELD, MASSACHUSETTS.

SPECIFICATION forniing part of Letters Patent No. 274,218, dated March 20, 1883,

' .Application tiled December 30. 1882. (No model.)

Be it known that I, W1LL1AM H. Paten, ot' Springfield. in the county of Hampden'and State ot' Massachusetts, have invented a new and useful Improvement iti Railway- Car- Wheels, of which the following is a specilication and description. n

The object ot' my invention is to provide a railway-car wheel whose side plates, made of wrought metal, are provided with retainingflanges, which are inserted each into an annular cavity made in the tirepand there secured by upsetting the `metal of the tire' against the outside ot' the plate, around its `outer edge, by which construction the ti're will be retained in place without the use of bolts inserted through the tire, and `this I accomplish by the construction substantially as hereinafter described, and illustrated in the accompanying drawings, in which- Figure l is a side view of a car-wheel made according to my invention. Fig. Ilis a transverse section through the tire and through a portion of the plates, showing the retainingilanges and the grooves in the tire to receive them before the tianges are secured therein; and Fig. lll is a transversesection of the Wheel at line A of Fig. l, showing the flanges of the side plates as secured in the annular grooves of the tire.

`1n the drawings, l represents the tire of a .car-wheel, in each side ot' which I forni an annular groove, 2. The side plates, 5, I form from wrought metal, both ofthe same or similar form, being circular, with an annular flange, 10, turned inward toward the tire at` the outer edge or rim, and this Aiiange is approximately iitted into its annular groove?. in the tire.

The hub 6 may be made from either cast or wrought metal, and is provided with an annular projection, 7, with a shoulder, 11, on each side thereof. The plates 5 are each bored or have a cenlral hole, 12, to receive the end of the hub, which is suitably titted therein,so that each plate 5, when in place, has a Iirrn bearing laterally against the side of the annular projection 7 and in the direction ofv the plane of the plate against the shoulder 11, and the plates are secured to the hub by bolts 9, each `inserted through holes made in the plates and in the hub therefor. Whonthe plates 5 are fitted to the hub their flanges l0 are also inserted into the grooves 2,and are there secured by upsetting the metal of the tire around each groove, as at .4., driving the outside of each plate at its rim, as shown at 4 in Fig. III. That part 3 of the tire which projects inward toward the hub forms an annular double flange, which supports .the outer portion of both plates, around their' rim, so that said plates have a firm bearing in the tire, and the hub, (which is bored to receive the aXle,) the plates 5, and the tire l are all rmly secured together.

If desired, the plates 5 may `be furthe braced by bolts inserted through them just inside the annular projection 3 of the tire, as shown in dotted lines in Fig. II; blut I do not deem it essential, inasmuch as the plates sethe grooves 2, as above described, with the each plate, forni a veryistrong connection for securing the tire to the plates,l and render the use of retaining rings or bolts inserted through the plates and through the tire entirely unnecessary for securing the tire to the plates. When secured in this manner, should the tire become cracked or a section thereofI entirely broken out,'even when in use, it will 'detached from the plates, as the anges will retairritin its position until such time as it could be repaired or a new Wheel substituted.

The metal otthe tire at 4 may he upset or turned against the plate by a hand-tool or by spinning itin by a rotarytool While the Wheel is being revolved, or by any other convenient means.

Having thus described my invention, what I claim as new is- The combination of the hub 6, provided with the annular flange 7, the tire l, having the annular projection 3, and provided on each side with an annular groove, 2, and the side plates, 5, centrally bored t0 receive the ends ot' the said hub, and provided with annular retaiuing tianges 10, inserted into said annular grooves inthe tire, and there secured by up- T. A. CURTIS, GHAs. H. WooD.

curedin the tire by inserting their flanges in be impossible for such broken part to become metal inward toward the hub and against the metal of the tire upset against the outside ot' IOO setting the-metal ot' the tire against the out- 4
